The Lowdown

Alright folks, Rusty here. Let’s take a look at the surf coming up for our little corner of the coast. The next 16 days start off real quiet, but there is a definite pulse of energy building for the start of September that’s got my attention.

We’ve got Karramarro, a point break that’s got a knack for picking up the NW swell. Don't get too excited for the first week though, because we're looking at a dry spell. From now until around Thursday the 27th of August, the waves are pretty much flat or gutless. You'll see tiny 0.3ft to 2ft wind slop with next to no energy (combined energy values under 100). It’s a tough stretch, but hold tight.

Things finally start to tick up on Thursday the 27th of August. The morning shows a bit of life with a 4ft NW swell, but the wind is cross-off, which will keep things clean, even if it’s not pumping. The afternoon is where it gets interesting: a 5ft WNW groundswell with a 10-second period rolls in, and we get glassy conditions. The combined energy jumps to 410 – that’s moderate energy starting to build. This is a sign of better things.

Friday morning the 28th of August has clean 4ft waves with a proper offshore wind from the SW, but it’s the period between Friday night and Saturday morning that’s the first real taste of what’s to come. Saturday morning the 29th of August is a standout for the near-term: absolute glass, calm wind, and a clean 5ft WNW swell. The water is sitting at 76°, which is much warmer than normal for this time of year – over 4° warmer than average, so you can leave the thick wettie at home.

Now, the real goods are waiting for early September. There is a gap of small, mediocre waves from the 31st of August through to the 3rd of September, but it’s a calm before the storm. On Friday the 4th of September, the ocean wakes up. The morning brings a solid 8ft NW swell with a 9-second period and light offshore wind. The combined energy is 842 – strong – and conditions look clean. This is the jump-off point.

The absolute standout of the whole forecast window is Saturday the 5th of September. The morning delivers a powerful 10ft NW swell (combined energy of 1433 – very strong wave energy), with a 10-second period, and clean offshore wind. This is proper, heavy surf. With the swell over 8ft, this is only for experts. This point break will be handling the size well, but the crowd factor is a concern here – Karramarro is often crowded, so get in early.

If you miss the peak, Sunday the 6th of September morning is still excellent. You’ve got glassy conditions and a 7ft NW swell with a 9-second period. Very good, clean surf. Then Monday the 7th of September morning throws a curveball: a 4ft WNW swell but with a very long period of 16 seconds. That’s a groundswell with serious energy (932 combined). On a point break like this, that long period is a dream, offering powerful, lined-up waves, though the sets will be more spaced out.

After that, the energy sticks around for the 8th of September, but the winds get a little messy. Still, for the first two weeks of September, we’ve got more action than we’ve seen all August.

To sum it up: sit through the flat spell this week. Your first real session is Saturday the 29th of August morning. But if you want the biggest, most powerful swell of the window, circle Saturday the 5th of September. It’s a big, expert-only day at Karramarro. Don’t sleep on Sunday the 6th or Monday the 7th either.

Stay stoked.
Rusty.

Information about the Karramarro Surf forecast

The above surf forecast table for Karramarro provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Karramarro can be found by selecting the local surf guide option on the grey menu. Our Karramarro surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (Karramarro) regularly then make a mental note of the wave energy from the surf forecast table each time you go. Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).

Further information to help with frequently asked questions about our surf forecast for Karramarro may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.

Karramarro is 3 km (2 miles) from Zarautz. If you plan a holiday in Pais Vasco, look for hotels and other accommodation in Zarautz. Zarautz has rooms for a wide range of budgets as well as car hire and transport links.
